Rated to 150 psi and 210 degrees F, this valve automatically opens to release excess pressure or heat before dangerous levels are reached. The body is constructed of brass with NPT male inlet and NPT female outlet connections. A test lever allows field verification of valve operation without tools. This model includes an 8-inch extension thermostat element, making it suitable for installations where the tank fitting is recessed or requires a longer probe reach. Licensed plumbers and HVAC service technicians are the primary installers of this valve.\u003c\/p\u003e\n\u003cp\u003eThe 100XL-8 3\/4 is rated for hot water supply systems up to 105,000 BTU\/h. It is used in residential and light commercial water heater installations and hot water storage tank applications where ASME-rated T and P protection is required. The thermostat features a special thermo-bonded coating. Standard pressure settings available include 75, 100, 125, and 150 psi. The 3\/4-inch connection size fits the inlet and outlet ports common on residential storage-type water heaters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTemperature relief set point: 210 degrees F (99 degrees C)\u003c\/li\u003e\n  \u003cli\u003ePressure relief range: 75 to 150 psi (5.2 to 10.3 bar)\u003c\/li\u003e\n  \u003cli\u003e8-inch extension thermostat element for deep-well tank fittings\u003c\/li\u003e\n  \u003cli\u003eBrass body with NPT male inlet and NPT female outlet connections\u003c\/li\u003e\n  \u003cli\u003eUnique thermostat with thermo-bonded coating for durability\u003c\/li\u003e\n  \u003cli\u003eTest lever included for in-service operational verification\u003c\/li\u003e\n  \u003cli\u003eASME rated and CSA listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with water heaters and hot water storage tanks up to 105,000 BTU\/h requiring 3\/4-inch T and P relief valve protection per ASME and CSA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with local plumbing codes and IFGC or IPC requirements as applicable. Shut off the water supply and allow the system to depressurize and cool before removing or replacing any relief valve. The discharge outlet must be piped to a safe drain location per code — never capped or plugged. Verify the replacement valve pressure and temperature ratings match the water heater nameplate before installing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 100XL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: NPT Male\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: NPT Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Relief Setting\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Relief Range\u003c\/strong\u003e: 75 to 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Relief Rating\u003c\/strong\u003e: 210 degrees F (99 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum BTU\/h Rating\u003c\/strong\u003e: 105,000 BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermostat Element Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Water Heater and Hot Water Storage Tank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: ASME Rated, CSA Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100XL-8 3\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51467430920498,"sku":"100XL-8 3\/4","price":76.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947182.jpg?v=1783904267","url":"https:\/\/voomisupply.com\/products\/watts-100xl-8-3-4-tp-relief-valve-150-psi-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
